Engineering Project Breakdown - 1 - Automatic Laser Turret

Ever wondered how the math you learn in school is actually used? Ever wonder what Engineers actually do? Watch how trigonometry, quadratic equations, and derivatives come together to assist me in building this laser-shooting robot! Uses a Raspberry Pi minicomputer, camera, and laser pointer to "shoot" targets in the surroundings Intro: 0:00 Demo: 1:00 Calculating XYZ: 2:50 (Linear Ratios, Regression, Equations, Pixels) Solving the Camera Angle Problem: 10:47 (Trigonometry) Analyzing the effects of Pixel Uncertainty: 16:27 (Derivatives, Trigonometry, Uncertainty) Dealing with Image Warping: 21:01 (Quadratic Equations) Determining Motor Angles: 23:26 (Trigonometry) Laser Electronics: 24:56 (Physics/Electricity) Conclusion: 27:00 Lessons/Takeaways: 27:42 Credits: 28:20 Code: https://github.com/EngJourney/Automat... Thumbnail created with images from www.freepik.com Edits: @ 20:31, I mislabeled the "region" we'd be operating in if the angle was bigger than 45 deg. As that angle increases, the tan(angle) will get bigger and bigger without bound (approaching infinity)!
